Fulfils a need, since a lack of literature in the field is apparent.

Diplomats are often considered to be masters of informality. Scholars and practitioners alike have long suggested that the real work of diplomacy happens in the corridor, during the coffee break and cocktail parties. But while everyone agrees that informality is a key ingredient of diplomatic work, few have explicitly explored it, and we lack a conceptualisation of how informality becomes meaningful. In this chapter, we unpack the question: through which spaces and practices is informality performed in diplomacy? Based on thick descriptions generated through ethnographic research in and around the institutions of the European Union (EU), we make two key contributions. First, we map local understandings of the term and give a grounded account of how diplomats use informality and interpret its functions. Second, we take these ‘tales from the field’ (van Maanen, 2011[1988]) and consider them in the light of theoretical debates on informality, particularly through the concept of boundary. Where and how is the boundary between the formal and informal constituted? Who has the power to draw and move these boundaries? How does it matter, politically, if something is ‘formal’ or ‘informal’? Based on our analysis, we find that informality comes in many forms and can be both politically productive and disruptive. In diplomacy, handling informality is a key diplomatic skill that is learned over time to be, eventually, mastered.

Children’s emerging conceptions about literacy and its functions are influenced by their experiences with a wide range of written and oral literacies, including the use of digital technology, in their homes and communities. Now that mobile technologies have become intuitive to use, relatively inexpensive, small and easy to move around and networked, they have provided an entry point for transformations in the creation and sharing of texts – they are changing the way young children ‘do’ literacy. In this chapter, the authors discuss the ways that children learn about multimodal texts; how mobile technology can facilitate the reading, creation and sharing of multimodal texts in preschool and primary classrooms; the literacy skills necessary for reading multimodal texts, and; strategies for planning instruction into which multimodal texts and mobile devices are integrated. Examples of how children may engage in multimodal reading and writing in and out of the classroom are also provided.

This chapter explores the evolution of the media framings of a corporate corruption scandal over time. Our analysis focuses on the evolution of media frames used by the English and French Press in the coverage of the corruption scandal involving SNC-Lavalin, a Quebec-based multinational engineering firm. We reveal how media coverage shifted from balanced and nuanced coverage of a complex phenomenon that facilitated debates on the appropriate consequences of corruption to a selective (re)construction of events to serve partisan agendas when the company’s legal plight was politicized. Our study contributes to the literature on media framings of corporate corruption by highlighting how the politicization of a corporate corruption scandal led to a dual climate of opinion across the English and French Press.

This article provides a detailed investigation of how Lewis revisited classical and Marxian concepts such as productive/unproductive labor, economic surplus, subsistence wages, reserve army, and capital accumulation in his investigation of economic development. The Lewis 1954 development model is compared to other models advanced at the time by Harrod, Domar, Swan, Kaldor, Solow, von Neumann, Nurkse, Rosenstein-Rodan, Myint, and others. Lewis applied the notion of economic duality to open and closed economies.

The kitting feeding policy creates kits with the parts of each product to assemble. Each kit contains elements with heterogeneous physical properties imposing heterogeneous logistic facilities and management solutions for storage and handling. The purpose of this paper is to present and apply a two-step procedure to design the part warehouse layout and to assign locations in case of kitting with high-variety part attributes. The proposed procedure aims at reducing the kitting travelled distance, shortening the picker paths, best positioning the components in the warehouse to enhance the possibility of creating kits through a single corridor access. The saturation of the warehouse and the minimization of the required storage space are also considered.

Starting from part categorization, the proposed two-step procedure, of general applicability, designs the component warehouse, sizing the corridors (Step 1) before clustering the kits in terms of part commonality and best-assigning clusters to corridors (Step 2) with the goal of reducing the travelled distance and saturating the available storage space.

A comparison model considers the traditional versus the proposed warehouse layout highlighting the potential saving in the picker travelled distance. A case study taken from the harvesting machine agricultural sector exemplifies the applicability and the practical implications of this research.

Elements of originality are the warehouse design strategy and the assignment model for parts based on their physical attributes and their occurrence in the assembly kits. Finally, the case study taken from industry, with a high number of components and part categories, adds value to the research making the proposed procedure able to address large-scale industrial problems.

The purpose of this paper is to provide the current state of the art in the development of a computer code combining an immersed boundary method with a conjugate heat transfer (CHT) approach, including some new findings. In particular, various treatments of the fluid-solid-interface conditions are compared in order to determine the most accurate one. Most importantly, the method is capable of computing a challenging three dimensional compressible turbulent flow past an air cooled turbine vane.

The unsteady Reynolds-averaged Navier–Stokes (URANS) equations are solved within the fluid domain, whereas the heat conduction equation is solved within the solid one, using the same spatial discretization and time-marching scheme. At the interface boundary, the temperatures and heat fluxes within the fluid and the solid are set to be equal using three different approximations.

This work provides an accurate and efficient code for solving three dimensional CHT problems, such as the flow through an air cooled gas turbine cascade, using a coupled immersed boundary (IB) CHT methodology. A one-to-one comparison of three different interface-condition approximations has shown that the two multidimensional ones are slightly superior to the early treatment based on a single direction and that the one based on a least square reconstruction of the solution near the IB minimizes the oscillations caused by the Cartesian grid. This last reconstruction is then used to compute a compressible turbulent flow of industrial interest, namely, that through an air cooled gas turbine cascade. Another interesting finding is that the very promising approach based on wall functions does not combine favourably with the interface conditions for the temperature and the heat flux. Therefore, current and future work aims at developing and testing appropriate temperature wall functions, in order to further improve the accuracy – for a given grid – or the efficiency – for a given accuracy – of the proposed methodology.

An accurate and efficient IB CHT method, using a state of the art URANS parallel solver, has been developed and tested. In particular, a detailed study has elucidated the influence of different interface treatments of the fluid-solid boundary upon the accuracy of the computations. Last but not least, the method has been applied with success to solve the well-known CHT problem of compressible turbulent flow past the C3X turbine guide vane.

This study’s goal was to identify how several markets have developed over time and what determinants have influenced this process, based on adaptive markets hypothesis (AMH). In this regard, the authors consider that agents are driven by the seeking for abnormal returns to stay “alive” and their environment could somehow modify their decision-making processes, as well as influence the degree of efficiency of the market.

The authors collected the daily closing-of-the-market index from 50 countries, between 1990 and 2022. The sample includes emerging countries, developed countries and frontier markets. Then, the authors ran multilevel modeling using Hurst exponent as an informational efficiency metric estimated by two different moving windows: 500 and 1,250 observations (approximately 2 and 5 years).

The results indicate that the efficiency of the markets is not constant over time. The authors also have identified that markets follow a cyclical pattern of efficiency/inefficiency, and they are currently in a period of convergence to efficiency, possibly explained by the increase in computational capacity and speed of the available information to agents. In addition, this study identified that country characteristics are associated with market efficiency, considering institutional factors.

Studies of this nature contribute to the literature, considering the importance of better comprehension of market efficiency dynamics and their determinants, specially observing other theories on the relationship between information and markets (like AMH), which work with other investor assumptions than those used by efficient market hypothesis.

Hailstorms are a major risk in agriculture. In order to mitigate the negative consequences on farm revenues, in the present paper the authors analyse the choice between insurance contracts and anti-hail nets. Furthermore, the authors discuss the consequences of anti-hail nets adoption on the actuarial soundness of the insurance market.

In this paper the authors firstly develop a theoretical model based on expected utility theory to compare the profitability of no-hedging against insurance and anti-hail nets. Subsequently, they test their theoretical model predictions with data of South Tyrolean apple producers.

The authors find that the benefit of anti-hail nets compared to insurance is an increasing function of the overall risk of hail damages, of the farmers' level of risk aversion and of the worth of the agricultural output.

Given the authors’ findings that anti-hail nets are more profitable for riskier, risk-averse and high-profitable farmers, the diffusion of anti-hail nets could be beneficial for the actuarial soundness of insurance markets.

The model developed in the paper is specifically designed to compare the profitability of different agricultural hedging options and can be easily extended to cover other hazards.
